T all whom t may conce/m.'

Be it known that l, HENRY l/V. TAGT- Mmm-.11, a citizen of the United States, re-' siding at Garrett, in the county of De Kalb and State of indiana, have invented a new and-useful Mutlier, of which the following is a specification.

This invention relates to mui'ilers to be used in connection with internal combustion engines, the primary object of the invention being to provide a muffler which may be readily and easily disassembled to replace parts or clean the same.

Another important object ot the invention is to provide a muiiier of la novel construction which will insure the muiing oi the exhaust gases passing from the internal combustion engine.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement ot parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment o't the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is a longitudinal sectional view through a muiiler constructed in accordance with the invention.

Figure 2 is asectional view taken on line 2-2 of Figure 1.

Figure 3 is a sectional view taken on line 3 3 of Figure 2.

Referring to the drawing in detail, the mutlier includes a cylindrical supporting section 5 or main portion, to which the cylindrical portion 6 is secured, the cylindrical portion 6 being smaller in diameter than the cylindrical portion 5 so that one end of the cylindrical portion 6 may be extended into the cylindrical portion 5 and riveted thereto as by means of rivets 7.

The reference character 8 indicates a head at one end of the muliier, which head is provided with a circular groove to accommodate one end of the cylindrical section 5 as shown by Figure 1, to insure a fluid-tight connection between the section 5 and head 8. Threaded socket members 9 and 10 respectively are bolted to the head 8 by means of bolts 11 the socket member 9 being internally threaded to receive the threaded end of the exhaust pipe 12 to which the mutller is secured. v

TArs'clearly shown by vFigureQ, the head 8 .is provided with a central opening to receive the rod 13 to be hereinafter more fully described, portions adjacent to the opening being cut away as at 14 to permit gases to pass into the muil'ler.A v

Positioned in the socketmember isl a tubular member 15 that is provided with a plurality of openings 16 through which the exhaust gases may pass from the tubular member 15. A threaded cap 17 closes the inner end of the tubular member 15 the cap being provided withk an opening to accommodate the rod 13 that is of a length to extend throughout the entire length of the muffler proper.

Arranged adjacent to the inner end of the tubular member 15 is a tubular member 18 that has connection with the supporting` member 19 which is riveted to the section 5 at 20. The discharge end of the member 18 extends into a tapered member 21 that is secured within the section 6 by means ot the rivets 7 that are employed for securing the sections 5 and 6 together, and as shown, this tapered member 21 is provided with Va plurality of openings 22 arranged adjacent to the secured end thereof so that exhaust gases must pass throughout the ent-ire length of the member 18 where they impinge on the end 23 of the tapered member 2O and are forced rearwardly to exhaust through the openings 22.

The outer end ot the muffler is closed by means of the head 2-1 that is provided with a circular groove to receive the outer end ot the section G and insure against gases passing betweeen the section 6 and head 24. An opening is formed in the head 24 for th-e reception of the rod 13, which rod is pro-- vided with threaded ends for the reception of the nuts 25 and 26 respectively that set up a binding action between the heads at the ends of the muffler to secure the various sections in their assembled positions.

A discharge opening 27 is provided in the sections 6 at a point adjacent to the head 241 so that the exhaust gases after they have been treated by the various elements of the mu'liler may pass outwardly therefrom and insure against the exhaust gases collecting in the muffler to retard the engine associated therewith.

`In view oi the foregoing detail descripsupporting'member-having a cent-ral open ing, a tubular member having afiia-nged eX- vtremity positionedy within the supporting member, a "removable tubular' `member -haveing openings arranged in the wall tthereof, thelast mentioned tubular member having a *threaded rearward extremity, a. cap removably supported on the Arearward vextremity 'of the lastmentioned tubular member, and

arranged adjacent. to the'iirstmentioned tubular member to restrict the passage of eX- haust thereto, va cylindrical member secured "td'tlie"rearward' 'endf the supporting section, a cone-'shaped member within the last mentioned cylindrical member, the first mentioned tubulark member having its rearward end disposed within the cone-shaped member, heads on the ends vof the muffler, one'of -the fheads having exhaust openings, and abolt extending throughthe muliler and oonineeted with the heads for holding the muffler together.

VIn testimony that I claim the foregoing as my own, I have hereto aiiixedy my signature.
